LibJS: Move resolution of some Intl.NumberFormat options to a common AO
This is a normative change in the Intl.NumberFormat V3 spec. See: https://github.com/tc39/proposal-intl-numberformat-v3/commit/29acfc6 This is to allow Intl.PluralRules to use these options, as they were in- effect required by later AOs anyways.
